Millimeter wave (mmWave) with large bandwidth is a key technology to support high-data rate vehicle-to-infrastructure (V2I) communications. In this paper, 28 GHz V2I channel is characterized for an urban street in Manhattan. By considering the recommendation in 3GPP TR 37.885, the transmitter is fixed on the street lamp with a height of 10 m, the receivers are mounted on top of the passenger car and bus with a maximum speed of 25 km/h. The ray tracing simulator with calibrated electro-magnetic parameters is employed in this work to practically conduct intensive simulations. The 3D environment model is reconstructed from OpenStreetMap. The key channel parameters, including the power delay profile, path loss, root-mean-square delay spread, K-factor, angular spreads and cross-polarization ratio, are analyzed and compared between different configurations. This work aims to helps the researchers understand the propagation channel for designing mmWave technologies and communication system in a similar scenario.
